MILK-BOTTLE OPENER.

Application filed July 15, 1922.

The invention resides in a novel tool or instrument for household use and more particularly in a convenient and efficient means for removing from and restoring to a milk bottle the usual pasteboard or paper disk customarily employed for sealing milk botties.

The tool or instrument of my invention is preferably in one integral piece of sheet metal and is in the form of a generally flat plate and comprises a reasonably broad handle portion and a head on the end thereof adapted to fit upon opposite portions of the lip of a milk bottle and having a depressed middle portion to enter the mouth of the bottle and formed with oppositely disposed spiral prongs which on a partial rotation of the instrument, when the same is in position on the bottle, will enter and become interlocked with the sealing disk, and thereupon when the instrument is lifted from the bottle the disk will be removed by and carried on said prongs against said depressed middle portion of said head. When it is desired to restore the sealing disk to the bottle, the disk while on the aforesaid prongs is by means of the instrument returned to its former position within the mouth of the bottle and the instrument is by a reverse partial rotation thereof caused to unscrew its prongs from the disk, thus leaving the disk and permitting the removal of the instrument without disturbing said disk. The sealing disk may thus be removed from and restored to the milk bottle by means of the one instrument. The instrument is of special construction so as to render its use both convenient and efficient.

I also preferably form the instrument with certain additional features so as to extend its scope of utility, and to this end I form on one side edge of the handle a crown-cap lifter and at the forward end of the device I form a reasonably sharp prong which may be used as an ice-pick or as a pick for other purposes.

The invention will be fully understood from the description hereinafter presented, reference being had to the accompanying drawings, in which:

Fig. 1 is a top view of an instrument embodying my invention, the same being shown as in operative position on a'milk bottle;

Fig. 2 is a vertical longitudinal section Serial No. 575,368.

through the same taken on the dotted line 22 of Fig. 1;

Fig. 3 is a vertical transverse section through the same taken on the dotted line 33 of Fig. 1, and

Fig. 1 is a forward end view of the instrument.

In the drawings, 10 designates the instrument of my invention as a whole and 11 an ordinary milk-bottle having a curved lip 12 around its mouth and at the base thereof a depressed annular shoulder 13 serving as a seat for the customary pasteboard or thick paper sealing disk 14:.

The instrument or milk-bottle opener 10 is preferably formed in one integral piece from sheet aluminum or other suitabie metal and comprises a reasonably broad fiat handle portion 15 and a forward head portion 16 which is of special formation and has a depressed middle portion 17 and curved portions 18, 19 at the ends thereof adapted to the curvature and circle of the lip 12 on the bottle and to seat on said lip and be capable of angular or rotary motion thereon. The degree of the depression of the portion 17 is such that said portion may reach the disk 1 1 while the end portions 18, 19 engage the lip 12 and guide said portion 17 to operative position. The depressed portion 17 has slit and pressed downwardly therefrom the opposite spiral or curved prongs 20, 21 which have reasonably sharp points and are adapted to be screwed into the paper disk 14-, as shown in Figs. 2 and 3.

In applying the instrument to use the handle portion 15 is taken holdof and with its use the head 16- is placed on the bottle with the curved portions 18, 19 positioned on the lip 12 and the depressed section 17 introduced downwardly into the mouth of the bottle until the prongs 20, 21 engage the disk 14, and thereupon while the instrument is rather firmly held on the disk 14, the instrument is given a partial rotary turn on the top of the bottle in a direction to screw the prongs 20, 21 into the disk 1 1, whereby the disk it becomes attached to the head 16 and may be lifted from the bottle by merely raising the instrument therefrom. After the desired quantity of milk has been poured from the bottle, the instrument carrying the disk 14 is replaced on the bottle and the disk is thereby returned to its seat 13, and thereupon and while the disk is firmly pressed against its seat, the instrument is given a reverse partial rotation to unserew or disengage its prongs 20, 21 from the disk and then lifted from the bottle, leaving the disk in its original position sealing the bottle.

The handle is formed with a hole 22 to enable the instrument to be hung upon a nail when not in use.

The handle 15 is broad and flat and may serve to carry suitable advertisement, and preferably 1 give to the handle 15 an outline indica ing approximately the profile of a mill: bottle, as shown in F 1.

For the sake of adding to the utility of the instri ment 1 form on one side edge of the handle 13 a Viwfi t the forward end of the instrument 1 t which is llO'i'lIfiOl'ltZLl and obvious kitchen purposes.

c aw to serve as a crown u litter, ed a .li from the curved end section 19 a prong may be used as an ice-piclr and for various The instrument described is preferably in shoe the form of a flat strip or blade or metal except atthe head 1% which is shaped to form the downwardly an inwardly eitendinp; curved bearing sections 18, ll) and depressed portion 17 carrying the prongs 20, 21, and by preference said head has parallel side edges and is less in width than the sealinp disk ll so as to ei-zpose portions of salt disk.

The mill; bottle opener hereinhefore described has been designed with the view of furi'iishin a light, cleanly, durable and ellicient household instrument at small manuiiacturing cost a .d. vhich could, if desired, be on to users of special brands of milk by reason of the abundant advertising surface the instrument affords.

"What I claim as my invention and desire to secure by Lottersi atent, is:

1. A milk-bottle opener of the character described formed from a flat strip of sheet metal, comprising in one integral piece a handle portion and a head on the end thereof having a depressed middle portion to seat within the mouth of the bottle and downwardly and inwardly extending curved sections at the ends of said depressed portion adap ed to engage and be given a turning motion on the rounded annular lip of the bottle, said depressed portion having oppositely curved prongs adapte el to be screwed into the paper disk sealingthe bottle, said depressed portion and said handle portion being" on parallel horizontal planes and said handle portion being elongated and adapted to be grasped within the hand.

2. A milk-bottle opener of the character described formed from a flat strip of sheet metal, comprising in one integral piece a handle portion and a head on the end thereof aving a depressed middle portion to seat within the mouth of the bottle and downwardly and inwardly extending curved sections at the ends of said depressed portion adapted to engage and be given a turning motion on the rounded annular lip of the bottle, said depressed portion having oppositely curved prongs adapted to be screwed into the paper disk sealing the bottle, said handle portion being of substantial width and Hat, and said head being less in width than the diameterof the sealing disk said depressed portion and said handle portion being on parallel horizontal planes and said handle port' in being elongated and adapted to be grasped within the hand.

3, A milk-bottle opener of the character described formed from a flat strip of sheet ietal, comprising in one integral piece a handle portion and a head on the end thereof having a depressed n'iiddle portion to seat within the mouth of the bottle and downwardly and inwardly extending curved sections at the ends of said depressed portion adapted to engage and. be given a turning motion on the rounded annular lip of the bottle, said depressed portion having oppositely curved prongs adapted to be screwed into the paper dislr sealing the bottle, said handle portion and. head being, in longitudinal alignment and on parallel horizontal planes and the forward down wardly and ii'lwardly extending curved section being also extended downwardly at its outer end to engage the outer-edge portions of said lip, and said handle portion be' lg elongated and adapted to be grasped within the hand.
